Used inside commands to schedule the propagation of additional commands * after the current command is propagated to AOF / Replication. * * 'cmd' must be a pointer to the Redis command to replicate, dbid is the * database ID the command should be propagated into. * Arguments of the command to propagate are passed as an array of redis * objects pointers of len 'argc', using the 'argv' vector.
